I need a short atheist phrase for a script tattoo.

I am getting a collar tattoo and I need some ideas for what to get. My best idea is "Beware of Dogma", but I don't want it to seem like a warning that I have dogma, so I'm thinking I should go in a different direction. Please post your ideas for a 3-5 word atheist phrase, whether it be funny, sarcastic, abrasive, or a combination of those. Thanks for your help!!

Tom Noonan has suggested "Good Without God", which is great. I translated it to Latin, "BonumSineDeus" and I think we have a winner. I'm going to have my tattoo guy draw it up in custom calligraphy. I will definitely post pics when it's done, along with pics of the other one. Stay tuned, my appointment is April 20th.

If you want something pithy and vague, but that will get people thinking, consider "Eppur si muove." As you may recall, this is the phrase that Galileo is said to have uttered after being forced to recant his statement that the Earth moves around the Sun, and not the other way around. Some say he uttered it directly to members of the Inquisition, and others contend that he said it upon being transferred from house arrest. Still, it's a great conversation starter, eh?
